Why Start With OEM

After reading that, you may have had one of many questions or doubts pop in your mind because of all of the opinions floating around on the web along with misleading marketing. Like:
- Subaru engines are prone to fail from the factory
- You need a closed deck block to make high power
- My bearings failed, so I need aftermarket ones. Or: My head gaskets failed so I need aftermarket ones.

The fact is, all of the above statements are not true. Click here to read our blog about what nearly 30 years of testing Subarus has proven.

*Please note OEM motors have a 3–5 business day lead time before shipping.

Want it better than stock? The Crawford BTO FA24 short block — this same OEM block with every bearing upgraded by Crawford.
